Card index



Sept. 20, 1932. K. A. A. JOHANSSON CARD INDEX Filed Jan. 3, 1931 l at ent ecl Sept 20, 1932 UNETED 'rT-Es teaser KARL ALB'IN ABRAHAM JoHANssoN, on s'rocxnoniu, swnnniv CARD I I Application filed January 8, 1931, Serial No tainers orboxes are arranged in a holder that ismounted to rotate on a shaft or axis.

A further object of the invention is to provide in such a device means for removably' attaching the boxes to the. carrier member;

and also to so arrange the boxes that the cards will be practically all located in radial planes;

that pass through the axis of the shaft.

Another object of the invention is to provide each of the boxes with a longitudinally extendingtube in its base, and a shaft is arranged to engage this tube to mount the boxes.

A further object is to provide a retaining frame between adjacent boxes to maintain them in proper positions.

In the accompanying drawing showing one embodiment of my invention,

Figure 1 is a transverse vertical section as seen on the line 1-1 of Fig. 2. r

Fig. 2 is a vertical axial section through the device.

As shown in the drawing the shaft 1 has two discs 2 and 3 secured thereto, the shaft being mounted on suitable arms l and 5 extending up from abase 6.

Between these discs are supported boxes denoted generally by 12, composed of a bottom wall 7 and side walls 8 and 9. Suitable curved pins 13 extend across between the side plates, for retaining the cards in the boxes.

In the'bottom wall 7 of each box is a series of tubes or sleeves 10 adapted to receive a'rod 14. This rod at one end enters a hole 11 in one of the discs 2. A sleeve nut 15 engages the other end of the rod 14, and is threaded into a bushing 17 mounted in the disc 3.

To further support the boxes, a series of channel-shaped frames '16 is extended across between the discs 2 and 3, that will engage INDEX .507,322, and in Sweden November 17, 1928.

the lower corners oftheboxes wheninserted;

:It will thus be seen that I have produceda comparatively simple device that comprises merely the'shaft and two perforated-discs, with the'boxes that consist merely of sheet metal bent up to achannel form" with the sleeves in the bases, and the retaining rods, with the simple bent plates inserted between the boxes, and the rods with the sleeve nuts.

The advantages of a structure ofthis character are that very thin cards may be used; also the insertion and removal of the cards is very easily efiected; and the division into different units isfacilitated, and any unit can be removed without disturbing the other units, andaeasily replaced or another sub- 7 stituted in the carrier.

It is obvious that modifications can be made within the scope ofthe claims of the invention. V

Having nowdescribed my invention, what I claim as new and desire to secure by Letters Patent is:

1. A card index device comprising a shaft with a pair of discs thereon, a series of channel-formed boxes, and means for removably mounting the boxes between the discs in a circular series, arranged to receive cards that are substantially parallel with axial planes of the shaft.

2. A card index device comprising a shaft with a pair of discs thereon, a series of channel-formed boxes, and means for removably mounting the boxes between the discs in a circular series, arranged to receive cards that are substantially parallel with axial planes of the shaft, said means comprising a series of longitudinal sleeves in the base of each box, and a rod located in said sleeves with its ends mounted in said discs respectively.

3; A card index device comprising a shaft with a pair of discs thereon, a series of channel-formed boxes, and means for remo-vably mounting the boxes between the discsjin a circular series, arranged to receive cards that are substantially parallel with axial planes of the shaft, said means comprising a series of longitudinal sleeves in the base of each box, and a rod located in said sleeves with its ends mounted in said discs respectively, one of the discs having an aperture to receive one end of each rod, the other disc having a threaded bushing, and a threaded sleeve mounted in said bushing to engage the other end of the rod.

4. A card index device comprising a shaft with apair ofdiscs thereon, a series of channel-formed boxes, and means for removab-ly mounting the boxes betweenthe discs in a circular series, arranged to receive cards that are substantially parallel with axial planes.
